Fibromyxoma of the axis
No full textFibromyxoma of bone is a rare benign tumor of fibrous tissue origin. The typical location is the jaws. Sporadic extragnathic cases have been reported, but fibromyxoma of the spine has not been reported. The histological appearance of fibromyxoma is benign and includes abundant extracellular fibrous and myxoid stroma with varying amounts of calcification and ossification. Myxoid changes are usually extensive. Extragnathic fibromyxoma of bone should be distinguished from benign cartilage-forming bone tumors, such as chondromyxoid and myxoid chondrosarcoma and myxoma of bone. It has also been suggested that fibromyxoma is a variant of myxoid fibrous dysplasia, whereas other authors reported extragnathic fibromyxoma resulting from myxoid degeneration of bone tumors, such as chondrosarcoma or fibrosarcoma. The overtreatment of patients with fibromyxoma of bone due to an aggressive imaging appearance should be avoided; the prognosis is excellent compared with the jaw variant and depends on the location and extent of the tumor. This article describes a case of a 21-year-old woman with fibromyxoma of bone originating from the spinous process of the axis. Clinical examination showed a tender mass in the midline of the posterior aspect the neck and slight limitation of neck range of motion; neurologic examination was normal. Diagnosis was obtained with a preoperative biopsy. Marginal excision of the lesion with posterior laminectomy of the axis was performed. The facets were preserved, and no fusion was performed. At last follow-up 2 years after diagnosis and treatment, the patient was asymptomatic with no evidence of local recurrence
Leiomyosarcoma of the hand
No full textSoft-tissue sarcomas of the hand are rare and the devastating effect of an undiagnosed sarcoma warrants clinical vigilance. We present the case of an unsuspected leiomyosarcoma localised in the hand in order to underline (i) the rarity of the disease in this site, (ii) the role of adequate surgical treatment in the first step, (iii) the relationship with adjuvant treatments, lymph node metastasis and the poor prognosis of this tumour.

Elastofibroma of the gluteal region with a concomitant contralateral lesion: case report and review of the literature
No full textA 51-year-old man presented with elastofibroma (EF) of the gluteal region with a concomitant contralateral lesion. The patient presented with a slow growing mass of the proximal third of the right buttock and had swelling, discomfort in sitting, and right-hip pain during walking for 2 months. On MRI, a soft-tissue mass was noted between the gluteus maximus and the gluteus medius muscle. The mass showed similar signal intensity to the surrounding tissue on T1- and T2-weighted images and with linear hyperintense areas in its internal structure. At surgery, a soft, non-encapsulated, irregular, and rubber-like mass was found attached to the gluteus medius muscles. It was pathologically confirmed to be an EF. This unusual manifestation of an EF is discussed
Myoepithelioma of the spine: first case in the literature.
No full textMyoepithelioma is a very rare tumour. This tumor type has been reported in the soft tissue, ear, sinonasal cavity, breast and lung. Although rare, myoepithelioma can occur in bone. We present the first case of myoepithelioma in the spine, documenting the clinical, radiographic and pathological features
